PRINTING DEVICE.

To all whom "it may concern:

Be it known that I, l/VILLIAM F. Amr STRONG, a citizen of the UnitedStates of America, residing at Pittsburg, in the county of Allegheny andState of Pennsylvania,-

have invented certain new and useful Improvements in Printing Devices,of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to a printing device, and the primary object ofthe invention is to provide a simple and inexpensive device lthan can beeasily attached to a paper roll holder for printing upon the paper as itis unwound and withdrawn from the holder.

Another object of this invention is to provide a printing device thatcan be advan tageously used by grocers and similar merchants for placingadvertisements upon wrapping paper or bags.

A stillfurther object of this invention is to provide a rotary printingdevice wherein provision is made for automatically inking the type roll.

These and such other objects as may hereinafter appear are obtained by aprinting device that will be hereinafter described in detail and thenclaimed.

In the drawings, Figure 1 is an end view of the printing device asconnected to a paper roll holder. Fig. 2 is a front elevation of aportion of the same. Fig. 3 is a cross sectional view of the printingdevice. Fig. 4 is a horizontal view of a portion of same. Fig. 5 is alongitudinal sectional view of an inking roll partly broken away. Fig. 6is an end view of a hand printing device partly broken away and partlyin section. Fig. 7 is an enlarged elevation of a portion of the same.Fig. 8 is a cross sectional View of a portion of the hand device.

In the accompanying drawings 1 denotes a base plate for standards 2 andrevolubly mounted in said standard is a roll of wrapping paper 3.

4 denotes a spring held pivoted shearing plate 4 supported by thestandards 2, said plate corresponding in length with the roll of paper 8and normally held in engagement with said roll whereby as paper isunwound it can be easily torn or severed from the roll. These parts arecommon to paper Specification of Letters Patent.

upon the paper as it is withdrawn from the roll.

5 denotes hinged members supporting a longitudinal bar 6, said hingedmembers being suitably connected to the bar 6 and to the plate 4.Attached to the bar 6 is a longitudinal casing 7 having the end walls 8thereof longitudinally slotted, as at 9 for spring pressed bearingblocks 10. The blocks 10 are adapted to engage the spindles 11 of atubular inking roll 12, said roll being perforated as at 13, and coveredwith a pad 14. One of the spindles 11 is provided with a bore 15normally closed by a threaded plug 16, said plug being removed when itis desired to till the inking roll 12.

Revolubly mounted between the end walls 8 of the casing 7 is a type roll17 having the periphery thereof provided with type 18, and the type issupplied with ink by theroll 12 normally bearing against the type. Themeans for holding the roll 12 against the type roll 17 are located inthe grooves 9, and such means as springs 19 are preferably employed.

'Ihe end walls 8 are provided with resilient guards 20 normally restinguponthe roll of paper 3, these guards supporting the type roll 17 out ofengagement with the roll 3, except when a piece of paper is being removed from the roll 3. The operation of removing a piece of paper has atendency to raise the plate 4 and cause the type roll 17 to engage theroll of paper 3. This 1s due to the fact that the guards 20 normallysupport the type roll 17 just clear of the paper roll, and as the freeend of the paper forming the roll is lifted to cut the same, the knife 4is lifted therewith, and being connected to the bar 6, pressuresufficient to overcome the tension of the guards 20 is exerted againstthe casing 7, so as to cause the type roll to be moved into engagementwith the paper, and as the knife 4 is held elevated by the paper duringthe time a strip of paper is being withdrawn and cut pli', the type rollwill revolve and make 1mprints on the paper during such revolution.

The hand device shown in Figs. 6 to 8 inclusive is similarly constructedwith the exception that the longitudinal bar 6 is provided with a handle2l, and a spiral spring 22 is located at one end of the type roll 17 forreturning the type roll to its normal position after it has been used,thereby preventing an advertisement from being printed backward.

My invention is applicable to various types of paper holders and can beused for numerous purposes, and While in the drawings there isillustrated the preferred embodiments of the invention, it is to be understood that the structural elements thereof can be varied and changedas to the shape, and manner of assemblage Without departing from thespirit of the invention.

Having new described my invention What I claim as new, is:

l. 1n a printing device for paper rolls, the combination With a framefor the paper roll, and a paper shearing knife pivotally supported fromthe frame and normally engaging the paper roll, of a printing devicecomprising` a casing overlying the paper roll, a bar secured to saidcasing at its lower end and hinged to said paper shearing knife, a typeroll journaled in said casing t the forward end thereof, an inkingroller also journaled in the casing and engaging the type roll, andresilient guards carried by the casing and engaging the paper' roll fornormally supporting the type roll free from engagement With the paperroll.

2. In a printing device for a paper roll, the combination with a framefor the paper roll, and a paper shearing knife pivot-ally supported fromthe frame and normally engaging the paper roll, of a printing devicecomprising a casing overlying the paper roll and hinged to the papershearing knife, and a type roller carried by said casing and heldnormally free from contact with the paper roll and adapted to engage thepaper roll when the shearing knife is lifted out of engagement With thepaper roll.

In testimony whereof I afiix my signature in the presence of tivoWitnesses.

WILLIAM F. ARMSTRONG.
